Primitive trailhead with access to motorized Grizzly-Helena Trail as well as Mount Zirkel Wilderness. The Lone Pine Trail is easy to follow through a few sections are fairly steep. This trail is difficult for horses. The Lone Pine Trail up to the Continental Divide and the route to Bighorn Lake are unimproved trails and maintained on a periodic basis. Campsites are scarce along the trail. This trail is very popular, so the opportunity for solitude is low.

About this trail's facts

The lines are the US Forest Service's National Forest System trails layer (public domain), read 2026-10-16 and simplified for the map; the length is the line's, end to end, and the class, surface, grade and tread width are the forest's own entries where it publishes them - a forest that publishes the centreline alone has none. The trailheads and the points along the way are the Service's recreation points, and the write-ups its own recarea text, unedited. Heights come from USGS 3DEP through Terrain Tiles on AWS (Mapzen/Tilezen), read along each line and rounded; a short trail on steep ground can be off by a few tens of feet. Closures change: check the forest's own site before you go.
